{"version":"1.0","type":"rich","title":"Hello VizHub","description":"This example demonstrates a minimal D3.js visualization that creates an empty SVG canvas. The code uses `d3.select` to append an SVG element to the body with a fixed width of 960 pixels and a height of 800 pixels. An empty `render` function is defined but not invoked, leaving the SVG blank. The visualization relies on D3 v5 loaded from a CDN and serves as a starting template for adding custom data-driven graphics.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
